Oxebar 1 gallon (4L) mini keg like a regular big bottle

[Ninoid]

Does anyone use the smallest one-gallon (4 liter) Oxebar keg as a regular large beer bottle in the sense of maintaining the quality and carbonation of the beer for at least a few days after opening and storing it in the refrigerator? The beer would be carbonated naturally with sugar.

i am not sure what you are asking but any pressurizable vessel can act as a large bottle. a corny keg is just a large bottle with the added benefit of having ball lock connectors.

but if you are just using it for a large bottle a 2 liter soda pop bottle with carb caps is basically the same thing
and works just as well. actually a little better than the 4 liter oxy's cause the oxis can sometimes have sealing problems.

so to answer your question, yes they could be used as a large bottle.

Yes, I understand that any plastic bottle can be used for beer, but I'm interested in experiences with resealing and loss of carbonation when used repeatedly over a few days.
There are commercial beers in 2L PET bottles that are not of the same quality as the same beers in glass bottles or aluminum cans, and the beer gets even worse if left in the fridge for a few days after opened.
Can an Oxebar PET bottle with thicker plastic and a better cap (at least that's what it says in the description) preserve beer better?

i dont think it will preserve any better than any other opened beer bottle. the oxygen ingress when opened is the same no matter what vessel you use.

i think the idea of the better preservation with these vessels as opposed to regular clear PET implies that the bottle isnt opened.

just get a mini regulator and sodastream and tubing / duotights and you have mini kegs. that will last the life of the gallon of beer in there even if drunk slowly.

The tapping heads can be tricky; the regular caps work fine. But any bottle of carbonated beverage will start to lose carbonation once you open it and pour the first glass. This is because the CO2 in the beverage is going to re-equilibrate with the headspace (which is now larger and no longer pressurized). If the beverage is beer, it will also start to oxidize. Unless you use the tapping head and re-pressurize the headspace after each pour.

Yes, that makes sense and I thought that was a bad idea, whatever bottle was used. Maybe I could try a bike pump instead of a CO2 bottle to start with. I read that air blown into the bottle doesn't affect the beer for a few days because of the pressure retention.

i have seen people use bike pump and there is actually a pump carb cap made for that purpose at morebeer and on aliexpress etc.

and i have seen it popular in UK. but i wouldnt trust my beer in contact with air. no matter the pressure. i think the bike pump idea is only for single uses. like if you are going to kill a keg in one sitting.

That page says to consume the beer within 24 hours. I can't find it online again now, but I've read that beer served from a keg with air was still good after a few days. It probably wasn't an IPA or some other oxygen-sensitive beer.

Yeah, it's basically like getting a commercial keg and using a picnic tap with a handpump. It's fine as long as you kill the keg in a day/night.
